 I never worked with [Storybook](https://storybook.js.org/) before, but I always wanted to try it. Storybook is an open-source tool for developing UI components isolated. It has a giant community creating plugins for every thinkable use case.
 
-I moved all my existing components to [Storybook](https://styleguide.stefanimhoff.de/) and started with a component-driven development. I created one story (a use case) for every component variation. Then I developed the components isolated from any website code in Storybook and unit tested the stories. This made the development much easier and fun than creating a manual [style guide](/styleguide/) page and developing the components on that.

Blissful ignorance from my side to all this data-driven, growth-driven, customer-satisfaction-driven development.

 <ProjectIntro>
 I rebuild my website in 2020, which was one of the biggest personal projects I’ve ever created. The process of researching, designing, and coding the website took me nearly **3 years** with **250 hours** of work. I wrote extensively about the [new website](/new-website-2020/), the [inspiration](/new-website-2020-inspiration/) behind it, the [design](/new-website-2020-design/) process, and the [development](/new-website-2020-development/) process. I wasn’t happy with the technical solution I picked in 2020 which was overengineered and too slow for a personal project. So, in 2021 I changed the static website generator from [Gatsby](https://www.gatsbyjs.org/) to [Eleventy](https://www.11ty.dev/). The [relaunch](http://localhost:8080/new-website-2021/) brought also smaller improvements to the font and simplified the overall website.
